Gelation of functional peptides by trivalent cations at the air-water interface
Stephen A. Crane, Felipe Jimenez Angeles, Monica Olvera de la Cruz +2
The paper describes how trivalent lanthanide ions cause peptides at the air‑water interface to switch from single‑peptide binding to multi‑peptide bridging, leading to a reversible…
A sweeping twist defect as a topological flagellum that drives colloid motion
Qi Xing Zhang, Claire Dore, Mojtaba Rajabi +2
Nematic liquid crystals can dramatically reconfigure under dynamic forcing, providing exciting opportunities in active matter. Here, we study a hybrid disk colloid rotated by an ex…
Scallop Theorem for Swimming in Anisotropic Fluids
Mojtaba Rajabi, Enej Caf, Qi Xing Zhang +5
In isotropic fluids like water, micrometer-scale swimmers have evolved swim strokes to translate despite their tiny size. As described by Purcell in his Scallop Theorem, reciprocal…
